What is the inverse of the function f(x)​
tresset_1 [31]

Step-by-step explanation:

For the inverse function put f(x) =y.

Then exchange x by y and then again separate y. The new value of y is the inverse function of f(x).

You have not written the value of function in the question so I have given just tips to solve it.

Correlation Coefficients. Image attached for the problem.<br><br> A. 11<br> B. 9<br> C. 3<br> D. 5
andreyandreev [35.5K]

Answer:

A

Step-by-step explanation:

y bar basically means the average of the y-values.

To get the average, we add up all the y-values in the table and divide by the total number of values (here we have 5 values). Hence,

y bar = \frac{5+7+10+15+18}{5}=11

correct answer is A

in 2003, a gallon of gas cost $1.75. In 2013 a gallon of gas cost $3.25. Write an equation to model this situation.
djverab [1.8K]

We can easily solve this by assuming a linear equation. The general form is:

y = m x + b

where y is the price of gas, x is the year, m is the slope or increase in price every year and b is the y-intercept

We can solve the slope by:

m = (3.25 – 1.75) / (2013 – 2003)

m = 0.15

 

y = 0.15 x + b

Using any pair data, we get the b:

3.25 = 0.15 (2013) + b

b = -298.7

 

y = 0.15 x – 298.7

If f(x)=x^2-81 and g(x)=(x-9)^-1(x 9), find g(x) * f(x)
ycow [4]
Hello,

if x≠9 then

f(x)=x^2-81\\\\&#10;g(x)= \frac{x+9}{x-9} \\\\&#10;&#10;g(x)*f(x)= \dfrac{(x-9)(x+9)(x+9)}{x-9} =(x+9)^2=x^2+18x+81
